How do you treat a STABLE pt with WIDE QRS tachy w/ pulse? For ex WPW or LBBB
ADenosine if regular.
Antirrhythmic
Consult
How do you treat STABLE pt with NORMAL QRS tachy w/ pulse? For SVT
IV,IO EKG, Vagal/valsalva massage, Adenosine if regular. Consult
This drug effect DEC HR and conduction velocity at AV?
Adenosine.
Other procainamide, amiodarone
What evaluate CO2 perfusion during CPR?
Capnogram
When should CPR be stopped in aystole PEA?
- Failure to respond
- time b4 collapse CPR and defib
- Length or resuscitation
- comorbid
- DNR
- Low end tidal CO2 after 20min of CPR
What are outcomes if fluid is pushing on heart?
Pericardial effusion w/ tamponade- low voltage/small QRS and T wave
ECG shows a reg QRS, then low QRS repeated, tachy. The pt has PHM of recent viral infection?
Cardiac Tamponade- ELECTRICAL ALTERNANS. Heart contracts harder and faster.
Clinically what are signs of pericardial effusion known as BECK triad?
- JVD*
- HYPOtension
- Muffled sounds
- Less CP if they lean forward.
- SOB,
What leads will determine low voltage of QRS-cardiac tamponade?
LIMB leads<5mm, Precordial <10mm in. Produce noise and heart compressed. Seen Normally in 1. Obese 2 COPD 3. Pericardial effusion 4. HYPOthyroid 5. Emphysema 6. MI damage 7. Infiltrative/restrictive dz
